Churn.



GEORGE KRIEGEL, OF BURROW-S, PENNSYLVANIA.

CHURN.

Specification of Letters Patent. I

Patented July 2, 1907.

Application filed September 29,1906. Serial No. 336,717.

To aZZ whom it may concern:

Be it known that I, GEORGE KRIEGEL, a citizen of the United States, residing at Burrows, in the county of McKean and State of Pennsylvania, have invented new and useful Improvements in Churns, of which the following is a specication.

This invention relates to churns and one of the principal objects of the same is to provide means for intermittently and alternately forcing air into the churn and withdrawing it therefrom to quickly convert cream into butter.

Another object of my invention is to provide a churn of simple construction which Will be provided with` means for forcing air into the churn and which will also be provided with reciprocating perforated dashers through which cream is forced during the operation of the churn.

These and other objects may be attained by means of the construction illustratedin the accompanying drawings, in which:

Figure 1 is a central vertical section through the churn body and showing the operating means in elevation. Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.

Referring to the accompanying drawing for a more particular description of my invention, lthe numeral l designates a cylindrical churn body provided with a fixed bottom 2 and a partition `3 secured at a point above the horizontal center of the churn body. A door 4 is located at the side of the chamber, a vertical support and guide 5 extended from the bottom 2 to the partition 3, said support and guide having a central air duct 6, said air duct communicating with an opening 7 at the bottom thereof which extends out through the opposite sides of the support and guide. An opening 8 in the partition 3 communicates with the duct 6 and resting upon the partition 3 is an air pump comprising cylinders 9 and 10, each provided with an inwardly extending pipe 11, 12, which communicates with a central air chamber 13 `fitted with a collar 11i. Flat valves 15, 16, are hinged within the chamber 13 to operate forwardly to establish communication between the cylinders 10 and the air chamber 13 through thepipes 11, 12, to the air duct 16, the air duct 6, and through the opening 7 into the churn. Pistons 18 are ittedvto the cylinders'9, 10, and are alternately reciprocated therein by means of cranks 19, 20, mounted upon the brackets 21 rising from the body'of the churn. The cranks 19 and 2() are connected eccentrically to gear wheels 22, 23, operated by means of a gear 24 mounted upon a crank shaft 25 operated by a hand crank 26. The piston rods 27 are connected to the pistons and to the crank shafts as shown in Fig. 1.

The connecting rods 28 are pivotally connected to the dasher rods 29, said dasher rods extending through the partition 3 and carrying at their'lower ends semicircular perforated dashers 30. Connected to the dashers 30 are upwardly extending guides 31which engage and slide upon the upright guideways 32 upon opposite sides of the support 5.

The operation of myinvention may be briefly described as follows: When the crank 26 is operated, the gear wheel 24 rotates the gears 22, 23, and through said gears cranks 19, 20, are actuated to reciprocate the pistons 1S in the cylinders 9, 10, and to simultaneously reciprocate the dashers 30. At the downward stroke of the piston 18 air is forced through the pipe 11 into the chamber 13 down through the duct 6 and into the churn through the opening 7. Atthe same time the dasher 30 is carried downward by means of the crank 19 and the cream is forced up through the perforation in the dasher. The dasher at the opposite side is being moved upward at the same time. l

From the foregoing it will be obvious that a churn made in accordance with my invention will agitate the cream by means of the dashers and the air forced into the churn and will convert the cream into butter within a short time'.

Having thus described my invention, what I claim is:

1. A churn provided with oppositely disposed air pumps and perforated dashers with means for alternately operating said pumps oppositely to force air into the churn and Withdraw the same therefrom intermittently.

2. A churn prov'ided With oppositely disposed cylinders, pistons in said cylinders, perforated dashers, and means for reciprocating said pistons and dashers alternately, substantially as described.

3. In a churn, the combination of oppositely disposed cylinders, pistons in said cylinders, perforated dashers, guides for said dashers, crank shafts to which said dashers and pistons are connected, and means for moving said dashers and pistons oppositely and alternately, substantially as described.

4. A churn comprising,l oppositely disposed perforated dashers, oppositely disposed cylinders, pistons in said cyliuders, and means to reciprocate one piston and one dasher simultaneously, and means for reciprocating the dashers and pistons alternately, substantially as described.

5. In a churn, the combination of a plurality of cylinders, pistons in the cylinders, dashers in the churn, means for operating the dashers and pistons simultaneously and alternately, air pipes connected to said cylinders, an air chamber communicating With said pipes, valves in said air chamber', and an air duct extending from the air chamber to the churn, substantially as described.

6. In a churn, the combination of a cylinder, a piston therein, a dasher, means for loperating said dasher and piston simultaneously, an air pipe leading from the cylinder to an air chamber, a valve in said air chamber and an air duct extending from said chamber into said churn, substantially as described.

7. In a churn, the combination of air pumps and dashers, and means for operating said pumps and dashers alternately.

In testimony whereof, I ax my signature in presence of two Witnesses.

GEORGE KRIEGEL.
